Electric charges will flow continuously only through a closed conducting loop called THIS
What is a circuit?
100
THIS circuit has only one path for electrons to flow. If one load burns out, the entire circuit is interrupted.
What is a series circuit?
100
Magnets have two poles know as THESE.
What are North and South?
100
A current-carrying wire wrapped around an iron core is called THIS
What is an electromagnet?
200
A material in which electrons cannot move easily from place to place.
What is an insulator?
200
THIS is the measure of how much electrical potential energy can be transformed into other forms of energy. Also known as the pressure of current through a circuit.
What is voltage?
200
Calculate the voltage when the resistance is 2 ohms and the current is 7 amps.
What is 14 volts?
200
THIS is the area surrounding all magnets in which magnetic forces can act.
What a magnetic field?
200
THIS is a device uses a magnetic field to turn kinetic energy into electrical energy.
What is a generator?
300
Metals such as copper, gold, sliver, and aluminum are examples of THIS type of material.
What is a conductor?
300
the measure of how difficult it is for electrons to flow through a material is called THIS.
What is resistance?
300
THIS circuit has more that one path for electrons to flow. If one load burns out, other parts of the circuit can still function.
What a parallel circuit?
300
A cluster of billions of atoms that all have magnetic fields that are lined up in the same way.
What is a magnetic domain?
300
In THIS type of current, electrons flow in one direction.
What is direct current?
400
THIS object can be used to protect a building from being damaged by a lighting strike.
What is a lighting rod?
400
This object allows you to open and close a circuit.
What is a switch?
400
If you have a battery and a lightbulb, you also need this to create a closed electric circuit where current can flow.
What is a conductor/wire?
400
Early explorers used THIS instrument which contains a magnet for navigation
What is a Compass?
400
The process in which an electrical current is induced by moving a permanent magnet through a coil of wire.
What is electromagnetic induction?
500
If a person has a build up of static electricity and touches another person they may feel a mild electric shock, what is the word that describes this rapid movement of of excess charges from on place to another?
What is electric discharge?
500
THIS instrument is used to supply energy to an electric circuit by converting chemical energy into electric potential energy.
What is a battery?
500
THESE prevent electric wires from overheating in your home.
What are fuses?
500
Opposites poles of a magnet does THIS while like poles do THIS. (TWO ANSWERS)
What are attract and repel?
500
THIS machine uses electromagnets to create images of the inside of a human body
